Subject Re: MySQL : No suitable driver found for jdbc:mysql
Date Wed, 18 May 2016 13:54:42 GMT
Nick,

mysql-connector-java.jar  was moved into the tomcat common.loader in /etc/cloudstack/management/catalina.properties:

common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar,/usr/share/java/mysql-connector-java.jar,/usr/share/cloudstack-mysql-ha/lib/*.jar

This was done to fix a bug where the mysql-ha feature was broken.

Does your common.loader  look similar to the above?

- Si

Subject: Re: MySQL : No suitable driver found for jdbc:mysql

Hey all,

So I've figured it out what's causing the issue, in
commit c22659d76d73f00f41c13776c490e17a50aacd20, there has been a change in
the classpath in cloud-management.sysconfig
The change removes the mysql-connector-java.jar from the classpath.

Before :
CLASSPATH=/etc/cloudstack/management:/usr/share/cloudstack-common:/usr/share/cloudstack-management/setup:/usr/share/java/mysql-connector-java.jar

After :
CLASSPATH=/etc/cloudstack/management:/usr/share/cloudstack-common:/usr/share/cloudstack-management/setup

Commit comment :  Addresses CLOUDSTACK-9300 where the MySQL HA
StaticStrategy class fails to load successfully

Does anyone have an idea why the mysql-connector-java.jar was removed from
the classpath?

Thanks in advance!
